A low-budget, exploitation film presented as a cautionary tale about the evils of white slavery prostitution rings operating in America's cities. Directed by Elmer Clifton who did the marijuana scare film "Assassin of Youth" the same year.
Here is the only noteworthy scene in this talky expose. For the first time in a mainstream film, spanking (and later cat-fighting) is shown as a sexual fetish -- in a brothel no less. The madam shows off her special Oriental room where two lingerie-clad prostitutes playfully grapple and smack each other. The scene also hints at mild masochism (and implied lesbianism) that is quite unique and remarkable for the 1930s. (This vintage film is in the public domain.)
This is part of a series of quasi-educational film clips on fetishism in cinema. Search for "fetish" and "stag film" to see more.
